I'm looking to buy the steel air injection tube the connects to the cylinder head between the exhaust manifolds on the USA M104 engine. This is shown as part 116 in the attached diagram. I just need it as a spare to make measurements and use as a template. If someone has a junk engine/head/car with this part on it and wants to part with it, please let me know. I would appreciate it.

Thanks,
